  • Extends USB-C connections with female-to-female design

Four-Pack USB-C Coupler for Multi-Device Setups

This set provides four female-to-female USB-C adapters, letting you join two male Type-C 3.1 cables or devices on each unit. It suits anyone extending a charging lead, linking a laptop to a hub or chaining video cables across a desk. Buyers needing male-to-female gender changers or legacy USB-A conversion cannot use these couplers.

40 Gbps USB4-Rated Bandwidth

Each adapter is rated for 40 Gbps data throughput, matching the USB4 specification. When paired with a USB4 cable the link can carry 8K resolution at 60 Hz for video and audio. Cables limited to lower USB generations will restrict the actual speed to their own ceiling.

100 W Power Delivery Under Continuous Load

The coupler handles up to 100 W of USB Power Delivery and negotiates the correct voltage and current automatically. It maintains that charge rate during extended sessions such as powering a MacBook while driving an external display, without requiring active cooling or driver software.

Questions about this item

What does the 40Gbps rating mean when I plug this adapter between two cables?

It allows the full USB4 bandwidth to pass through so a connected host and device can reach 40Gbps if both ends and the cables also support USB4.

Which interface standard does the coupler use and what does it limit in practice?

The adapter follows the USB4 specification and caps throughput at 40Gbps, power delivery at 100W and video at 8K 60Hz when paired with compliant cables and hosts.

What physical connection does each side need to fit this adapter?

Both sides require a USB-C 3.1 male plug; the adapter provides two female ports that accept those plugs directly.
